If the sanitary conditions in your unit are such that it attracts pests of any kind, and it becomes necessary for us to undergo remediation in the building, you will be held financially responsible for reasonable costs thereof, paid as additional rent.Please let me know what you have learned over the years about putting specific items in your least to protect you as a landlord. 

If the sanitary conditions in your unit are such that it attracts pests of any kind, and it becomes necessary for us to undergo remediation in the building, you will be held financially responsible for reasonable costs thereof, paid as additional rent.I know some have stated above that this is unenforceable with MF properties, but what I would do is inspect all contiguous units to this one and take pics of the housekeeping quality. 

If you are wanting to successfully do a BRRRR - this is the formula you need to run "back of the napkin" for every property you look at:Cap Rate(Anticipated Rental Income * 12) * .6 - this will give you "Net Operating Income" for the year with a 40% hedge for expenses.Divide that by the purchase price gives you a cap rate.     

I was young so I drew it up on a napkin.

It’s ok for a quick napkin calculation to determine if I want to dig deeper.  

A dye test is carried out by a plumber to make sure that the gutters of the house are not tied into the sanitary sewers.

Some of those variables are the size of the park, number of vacant spaces, number of POHs, number of vacant POHs, number of MH spaces, number of RV spaces, the park amenities, the age of the park, underground infrastructure age and condition, park location, size of the market, value of SFR in the market, water or well, sewer or septic, other utility sources and whether or not they are direct billed, deferred maintenance, cost of management, and more.However, there is a basic "back of the napkin" evaluation that will usually tell you if the deal is worth a closer look.

Seems like you guys are good candidates back of the napkin for what you provided. 

(a) A landlord shall:(1) comply with the requirements of applicable building and housing codes materially affecting health and safety;(2) make all repairs and do whatever is necessary to put and keep the premises in a habitable condition;(3) keep all common areas of the premises in a clean and safe condition;(4) maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, air-conditioning, and other facilities and appliances, including elevators, supplied or required to be supplied by the landlord;(5) provide and maintain appropriate receptacles and conveniences for the removal of garbage, rubbish, and other waste incidental to the occupancy of the dwelling unit and arrange for their removal; and(6) supply running water and reasonable amounts of hot water at all times and reasonable heat except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection.

On my back of a napkin analysis you might be overpriced based on the micro-climate of this specific neighborhood.
